Definitions

  • the device in accordance with the invention is characterized in that there is provided in the drain pipe an antifoam valve member which can move only in one direction, which is constructed and acts in such a way as to be brought under the weak thrust of waste water in the open position and which can resume a vertical position and be maintained against a locking surface through the forces of gravity and elasticity.
  • foam value consists of a diaphragm of flexible material, rubber for instance, in the form of a washer whose periphery is gripped, forming a joint between two components provided on the drain pipe and which has over about 300 of its circumference an annular recess interrupted over about 60 in such a way as to form a hinge and the een tral part forms the anti-foam valve which can only move in one direction.
  • FIGURE 1 is a section showing the device with the valve closed.
  • FIGURE 2 is a similar view with the valve open.
  • FIGURES 3 and 4 are detail views.
  • FIGURES 5 and 6 represent improved forms of the invention.
  • the device comprises three components I-II-III of metal, plastics or other material.
  • the component I an inlet component, comprises a cylindrical portion 1 provided with an external screwthread 2 whereby it may be connected to a trap 3 on the side of the trap connected for instance to a sink 4 (FIG- URE 4).
  • This component I terminates on the side opposite the drain pipe in a flange 5 presenting a support surface 6 which will be referred to below and which is bent back towards the pipe 3 to present a cylindrical projection 7 concentric with the portion 1 and provided with a male screwthread 8.
  • the component II has an externally threaded extension 9 for connection with a drain pipe 10 leading to a downpipe 11 (FIGURE 4).
  • the extension 9 is eccentric with respect to the component I in order to avoid deposits forming at the bottom and side of the pipe 1.
  • the component II is widened (at12) to present a chamber 13 permitting the movement of a diaphragm 17 which will be referred to below.
  • the widened part 12 terminates in a radially directed flange 14.
  • the component III is an internally threaded connecting member 15 which screws onto the threaded projection7 and is provided with a rim 16 which engages behind the flange 14.
  • a flexible diaphragm 17 in the form of a washer (FIGURE 3) of rubber, for instance, and which has its periphery gripped to form a joint between the flangcs 5 and 14.
  • a slot 18, concentric with respect to the periphery of the diaphragm extends through about 300 and is interrupted over about 60 in the upper part at 19 (angle a, FIGURE 3) in such a way as to form a hinge at this point.
  • the central portion 20 of the diaphragm forms a valve member.
  • valve 20 When the flow ends the valve 20, through its own weight and elasticity, resumes the position shown in FIGURE 1 and it is maintained in this position a fortiori under the counterpressure exerted by the foam against the blocking face 6 which prevents it from moving in the direction oppositc that represented in FIGURE 2.
  • FIGURE 5 makes it possible to considerably reduce the cost of production and installation, giving rise to an assembly comprising the trap mandatorily arranged below the lavatory in order to prevent the backrise of bad smells and the foam-checking device described above.
  • the inlet component of the anti-foam device and the piece forming the outlet of the trap form a single tube with a male thread on which the threaded connection for locking the foam-checking device is screwed.
  • the body of the trap and the cylindrical inlet com material-and constituting a monoblock The body of the trap and the cylindrical inlet com material-and constituting a monoblock.
  • FIGURE 5 the-re is shown at 1 the cylindrical portion of the inlet component which provides by means of a cylindrical projection 7 concentric to this portion and connected to it by a flange 5, a support for the flexible diaphragm 17 in the form of a washer having the characteristics mentioned above and whose central portion forms the valve member 20 moving in the chamber 13 formed by the widened portion 12 of the connecting member II connected by a screwthread 9 with the connecting pipe for the downpipe.
  • the air trap comprises the telescopic waste inlet pipe 21 connected to the lavatory or sink by a locknut 22 and a joint 28 and slidingly arranged in the inlet pipe 23 which forms one piece with the body 24 of the trap provided with the trap outlet component 27; a nut 25 locks the telescopic pipe 21 on the inlet pipe 23 and fluidtightness is ensured by a joint 29.
  • a movable and dismountable base 26 is screwed to the base of the body 24 fluidiightly thanks to the joint 30.
  • the inlet pipe 23 is eccentric in known manner in the body 24, so that when water flows a turbulence is created, the result of which is always to leave after this flow a water level above the lower end of the inlet pipe 23 the V result of which is to prevent bad smells rising back.
  • the inlet component 1 of the anti-foam device and 27 constituting the trap outlet form a single pipe
  • the trap body 24 and the cylindrical inlet component 1 of the anti-foam device may form a single element, generally produced by moulding from a synthetic material.
  • valve of the flexible diaphragm is formed and acts as described above without however this embodiment which may be improved constituting a restriction;
  • the valve may for instance be reinforced by a stainless steel plate 31 so as to render it more rigid and thus able to prevent the return of waste water in addition to foams;
  • the diaphragm may be made of rubberized fabric or any other equivalent material, or again the cylindrical portion 1 may be chamfered in such a way that the valve 20 rests slightly obliquely in the closed position of the device (see FIGURE 6) because it may happen that because of the ageing of the rubber, the
  • valve 20 losing some of its elasticity does not fall completely back into the vertical position under its own Weight, thus leaving a passage for the rising of the foam.
  • FIGURE 6 shows an improved embodiment of the invention similar to the preceding.
  • the inlet component 1 of the anti-foam device and the component 27 forming part of the trap no longer constitute a single pipe; the inlet component 1 screws on the trap outlet pipe 27; thus the trap and the cylindrical inlet component of the anti-foam device no longer form a monoblock assembly which offers the advantage commercially of being able to sell a trap or anti-foam device independently of one another, or the two appliances screwed together may be sold as a unit.
  • All the parts of the device in their improved embodiments are preferably made of a transparent synthetic material, for instance cellulose polyanate, but may quite well be made of another material.
  • an anti-foam device situated in said drain-pipe to prevent the rising and backflow in said sinks of foam coming from waste water; said device comprising an inlet connected up-stream to said drain-pipe, an outlet connected downstream to said drain-pipe, a diaphragm having an annular slot over substantially 300 of its circumference delimiting a central disc-like portion, an annular outer portion, and a hinge between said disc-like portion and said annular portion, said central disc-like portion constituting a valve member, means for allowing movement of said valve member in one direction under the thrust of waste Water from said inlet and for preventing movement of said valve member in a reverse direction against the thrust of 'backfiow of foam from waste water in said outlet, interconnecting means for said inlet, outlet, and annular portion.
  • said interconnecting means includes an outer annular member with screw threads and a flange on opposite ends, a cylindrical screw thread projection on said inlet, and a flange on said outlet.
  • a drainage system in which the inlet includes a trap body and forms therewith a one-piece element.
  • a drainage system according to claim 1 in which a stainless steel plate reinforces said diaphragm in such a way as to render it more rigid and to enable it to prevent the backfiow of waste water as well as foam.
